Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dryer for drying clothes by dehumidifying air or for drying a bathroom, a closet, or a room.

[0002]

2. Description of the Related Art A clothes dryer conventionally used is shown in FIG.
The structure is as shown in FIG. That is, the air blowing means 5 circulates and blows air using the circulation air passage 3 through the adsorbent 2 into the drying chamber 1 that houses clothes that can be assembled freely from, for example, vinyl. As the blowing means 5, for example, a sirocco fan is used. As the adsorbent 2, silica gel or zeolite is used. Reference numeral 4 denotes a regeneration air passage for guiding air outside the drying chamber 1 to the adsorbent 2 and guiding the air outside the drying chamber 1 again. Air path switching means 7 and 8 constituted by a damper or the like switch between the circulation air path 3 and the regeneration air path 4. The heating means 6 is arranged on the windward side of the adsorbent 2 and supplies high-temperature air to the adsorbent 2 when energized by an instruction of the control means 9. By the supply of the high-temperature air, the adsorbent 2 releases the adsorbed moisture and is regenerated. That is, when the control unit 9 recognizes that the total of the adsorption time of the adsorbent 2 has reached the predetermined time, the control unit 9 regenerates the adsorbent 2 by energizing the heating unit 6. In this regeneration step, the control means 9 activates the air path switching means 7 and 8 so that the regeneration air path 4 side is opened and the circulation air path 3 side is closed, so that the humid water containing the moisture adsorbed by the adsorbent 2 is obtained. Without circulating the air in the drying chamber 1,
The air is discharged from the drying chamber 1 through the regeneration air passage 4.

With the above arrangement, when a user operates an operation unit (not shown) to start operation, the control means 9 causes the air path switching means 7 and the air path switching means to open the circulation air path 3. 8
The air blowing means 5 is operated in a state in which is operated. By the operation of the blowing means 5, the air in the drying chamber 1 repeats the circulation to be blown to the drying chamber 1 again via the adsorbent 2. At this time, the air that has passed through the adsorbent 2 is dehumidified by adsorbing moisture by the adsorbent 2, and at the same time, becomes high temperature and low humidity by the heat of adsorption generated by the adsorbent 2. The high-temperature and low-humidity dry air circulates in the drying room 1 containing clothes such as laundry, thereby replacing the humid air due to the humidity from the clothes and bringing the high-temperature and low-humidity air into contact with the clothes. Thereby, drying of the clothes such as laundry stored therein progresses. When a predetermined time has elapsed since the start of drying, the control means 9 controls the air path switching means 7.
And the air path switching means 8 are operated to open the reproduction air path 4. At the same time, the heating means 6 is energized to heat the air outside the drying chamber 1 which the blowing means 5 blows. The heated air comes into contact with the adsorbent 2 to heat the adsorbent 2 and release moisture adsorbed by the adsorbent 2. The released moisture is discharged from the drying air passage 4 to the outside of the drying chamber 1 by the blowing of the air blowing means 5 because the regeneration air passage 4 is open. Thus adsorbent 2
Is regenerated and the water adsorption capacity is restored. The adsorption and regeneration as described above are repeatedly performed by the control means 9, and the drying of clothes such as laundry stored in the drying room 1 proceeds.

In the above description, the drying room 1 has been described as accommodating clothes that can be assembled with vinyl or the like. However, if the drying room 1 is treated as a room in a house such as a bathroom or a closet, It is a bathroom dryer and a push-in dryer of exactly the same configuration.

[0005]

The above-mentioned conventional clothes dryer, bathroom dryer, and push-in dryer have a problem of low energy efficiency. That is, the air after the regeneration of the adsorbent by the heating means has a high temperature even after the regeneration, and this energy is exhausted from the regeneration air passage to the outside of the drying chamber. Further, the regeneration air discharged outside the drying chamber is humid, and has a problem of increasing the humidity outside the drying chamber.

[0006]

According to the present invention, a heat exchanger is provided for exchanging heat between regenerated air sucked from outside the drying chamber and air after regenerating the adsorbent. The heat energy of the regenerated air to be used can be effectively used, and the dryer has high energy efficiency. Further, by cooling the regenerated air with air outside the drying chamber, the degenerated air is condensed, the moisture of the regenerated air is reduced, and the regenerated air is discharged outside the drying chamber.

[0007]

(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a sectional view showing the configuration of the present embodiment. Numeral 10 denotes a drying room which is formed freely from vinyl or the like for accommodating clothes such as laundry, or a room in a house such as a bathroom or a closet. (In the following description, it is assumed that the drying room 10 stores clothes such as laundry.) A circulating air path 12 formed by a duct or the like is connected to the upper and lower portions of the drying room 10. In the circulation air passage 12, the first
A blowing unit 14, an adsorbent 11, and a heating unit 15 are provided. In the present embodiment, the first blower 14 uses a centrifugal blower, and circulates air sucked from the drying chamber 10 into the drying chamber 10 again via the adsorbent 11. is there. A heating means 15 is arranged on the windward side of the adsorbent 11.

In the middle of the circulating air passage 12, a regeneration air passage 13 constituted by a duct or the like is provided.
The regeneration air passage 13 is connected to the circulation air passage 12 via air passage switching means 17 and 18 constituted by dampers and the like. The air path switching means 17 and 18 operate according to an instruction from the control means 21. The state shown by a solid line in FIG. 1 indicates a state in which the circulation air path 12 is shut off and the regeneration air path 13 is used. ing. On the other hand, the state shown by the dotted line shows a state in which the recirculating air path 13 is shut off and the circulating air path 12 is used. A plurality of heat exchangers 1
9a and 19b are provided. In other words, the air outside the drying chamber 10 that has been sucked in from the suction port 13a by the second blowing means 18a is heated by the heating means 15 and
And heats the adsorbent 11, passes through the heat exchanger 19a and the heat exchanger 19b, and is exhausted from the exhaust port 13b. At the same time, a cooling air passage 42 is connected to a part of the regeneration air passage 13. In the cooling air passage 41, the heat exchanger 19b and the second blowing means 18b are arranged. That is,
The air outside the drying chamber 10 sucked by the second blowing means 18b from the suction port 42a is exhausted through the heat outlet 19b through the heat exchanger 19b.
It is exhausted from. As a result, the heat exchanger 1
The air flowing from the outlet 9b to the exhaust port 13b is further cooled and becomes low in humidity.

The regeneration air passage 13 has a drain hole 22.
a, 22b are provided, and the dew water generated in the heat exchangers 19a, 19b is discharged out of the system.

The first blowing means 14, the second blowing means 18a,
Although a centrifugal sirocco fan is used in this embodiment as 18b, it is not particularly limited to a centrifugal sirocco fan. In this embodiment, the adsorbent 1
1 uses a molded product of silica gel or zeolite. The heating means 15 is constituted by a nichrome heater, a ceramic heater having a positive resistance temperature coefficient, or the like.

The operation of this embodiment will be described below. When the user starts operation by operating an operation unit (not shown), the control means 21 controls the air path switching means 16 and the air path switching means 1.
7 to open the circulating air passage 12 and simultaneously operate the first blowing means 14. By the operation of the first blowing means 14, the air in the drying chamber 10 is circulated using the circulation air path 12 provided in the upper part of the drying chamber 10 and the lower part of the drying chamber 10. The adsorbent 11 is disposed in the circulation air passage 12.
Therefore, the circulating air blown by the first blowing means 14 always comes into contact with the adsorbent 11. Due to this contact, the air that has passed through the adsorbent 11 is dehumidified by the moisture contained in the air being adsorbed by the adsorbent 11, and at the same time
Is generated to obtain high-temperature, low-humidity dry air by the adsorption heat generated. Thus, the high-temperature and low-humidity dry air supplied from the lower part of the drying room 10 functions to dry clothes such as laundry stored in the drying room, for example. The low-temperature and high-humidity air including the moisture evaporated from the clothes due to the contact with the clothes such as the laundry is sucked in from the upper part of the drying chamber 10 by the first blowing means 14, and again the adsorbent 1
1, the air is supplied to the lower part of the drying chamber 10 as high-temperature, low-humidity dry air. Thus, the circulation of the dry air using the circulation air passage 12 replaces the moist air in the drying chamber 10 with the dry air, and the drying of clothes such as laundry in the drying chamber 10 proceeds. When the drying room 10 is a room in a house such as a bathroom or a closet, the drying of the bathroom or the closet proceeds.

In this embodiment, when a predetermined time has elapsed from the start of drying, the control means 21 operates the air path switching means 16 and the air path switching means 17 to close the circulation air path 12 and regenerate the air. An instruction is made to open the road 13. That is, adsorbent 1
When the device 1 adsorbs a large amount of water and its adsorbing ability is lowered, the regeneration process is executed. In this regeneration step, the adsorbent 11 is heated by the heating means 15 and a large amount of water adsorbed by the adsorbent 11 is released from the adsorbent 11 to regenerate the adsorbent 11. In this regeneration step, the control means 11 gives an instruction to energize the heating means 15 simultaneously with the operation of the air path switching means 16 and the air path switching means 17. Therefore, the regenerated air sucked from the suction port 13a provided outside the drying chamber 10 by the second blowing means 18a passes through the heat exchanger 19a, is heated by the heating means 15, becomes high temperature, and comes into contact with the adsorbent 11. I do. The contact of the high-temperature air raises the temperature of the adsorbent 11, and the moisture absorbed by the adsorbent 11 during the circulation is reduced by the adsorbent 1.
Released from 1. The humid regenerated air containing the released water passes through the regenerative air passage 13 and passes through the heat exchanger 1.
9a, the air is exhausted to the outside of the drying chamber 10 from the exhaust port 13b through the heat exchanger 19b.

At this time, in the present embodiment, as described above, the regeneration air passage 13 is provided with two heat exchangers 19a and 19b. The heat exchanger 19a acts to preheat the air outside the drying chamber 10 sucked from the air inlet 13a. That is, the air heated to a high temperature by the energization of the heating means 15 uses most of the heat energy by heating the adsorbent 11,
When it reaches the heat exchanger 19a, it still has considerable heat energy. Therefore, in this embodiment, the heat energy is exchanged with the air outside the drying chamber 10 sucked through the air inlet 13a using the heat exchanger 19a. As a result, the air outside the drying chamber 10 sucked from the suction port 13a is heated, so that the heating means 1
In this embodiment, condensed water generated in the heat exchanger 19a passes through the heat exchanger 19a, and is discharged out of the system through the drain hole 22a to dry dry air. Is a heat exchanger 1 as described above.
The condensed water generated through the passage 9b is discharged to the outside of the system through the drain hole 22b, and then discharged to the outside of the drying chamber 10 through the discharge port 13b. At this time, the heat exchanger 19b
The second blower 18b exchanges heat between the cooling air outside the drying chamber 10 sucked from the inlet 42a and the air passing through the heat exchanger 19a. By the heat exchange using the cooling air passage 42, the air that has passed through the heat exchanger 19b has a lower humidity. Condensed water generated by heat exchange is discharged out of the system from the drain hole 22b. In addition, the second blowing means 18b
The cooling air sucked by the heater is heated and slightly rises in temperature, and is exhausted out of the drying chamber 10 through the exhaust port 42b.

That is, according to this embodiment, heat is transferred between the regenerated air before heating and the regenerated air whose temperature is high and humid due to the residual heat after the regeneration, and the heat exchanger 19a. On the other hand, the air outside the drying chamber 10 sucked by the second air blowing means 18b is sent to the heat exchanger 19b through the cooling air passage 42, and exchanges heat with the regenerated air after passing through the heat exchanger 19a in the heat exchanger 19b. Thus, the regeneration air is further cooled.

As described above, according to the present embodiment, the adsorbent 1
1 is passed through the humid and relatively high temperature regenerated air using the heat exchanger 19a.
By exchanging heat with the air outside the drying chamber 10 at a relatively low temperature before passing through, the heat energy of the regenerated air including the sensible heat and the latent heat can be recovered.

As a result, the temperature of the air blown to the heating means 15 becomes higher than the temperature of the air outside the drying chamber 10, so that the heating means 15 for raising the temperature of the regenerated air to a predetermined temperature is consumed. The power can be reduced. That is, a dryer with high energy efficiency can be realized.

Further, in this embodiment, the air passing through the heat exchanger 19a is exchanged with the outside air by using the heat exchanger 19b, so that the humidity of the air passing through the heat exchanger 19a is further reduced. That's what we do. For this reason, the dryer is designed to prevent an increase in humidity outside the drying chamber 10.

In this embodiment, two heat exchangers 19 are used.
Although a and 19b are used, there is no problem even if two or more heat exchangers are used, and the number of heat exchangers used is not particularly limited to two.

In this embodiment, the second blowing means is 18a.
And 18b, but the same effect can be obtained with two or more units. Although a motor and a sirocco fan are used as the first blowing means 14 and the second blowing means 18a, 18b, the present embodiment limits the configuration of the first blowing means 14 and the second blowing means 18a, 18b. is not. Further, the first blowing means 14 and the second blowing means 1
Although a motor is used for each of the motors 8a and 18b, it is also possible to use a single motor and rotate two or three fans. Also,
The installation positions of the first blowing means 14 and the second blowing means 18a, 18b are not particularly limited as long as the air in the drying chamber 10 or the air outside the drying chamber 10 can be blown in a predetermined direction in each air path. It does not do.

(Embodiment 2) Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a sectional view showing the configuration of the present embodiment. Portions common to the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the present embodiment, 1
Two heat exchangers 20 are arranged. In this embodiment,
The number of the second air blowing means 43 is one, and internally partitions the regeneration air passage and the cooling air passage described in the first embodiment. That is, the drying chamber 1 is
The air taken in from outside passes through the heat exchanger 20 and one is sent to the heating means 15 as regeneration air, and the other is sent as cooling air from the exhaust port 42 b or 42 c to the drying chamber 1.
It is exhausted outside zero. This cooling air further cools the regeneration air in the heat exchanger 20. Also,
Reference numeral 21 denotes a control unit that controls each unit. Reference numeral 23 denotes a drain hole provided in the regeneration air passage 13 for discharging dew water generated in the heat exchanger 20.

In this embodiment, a centrifugal sirocco fan is used as the second blower means 43. However, the present invention is not limited to the centrifugal sirocco fan.

Hereinafter, the operation of this embodiment will be described. When the user starts operation by operating an operation unit (not shown), the control means 21 controls the air path switching means 16 and the air path switching means 1.
7 to open the circulating air passage 12 and simultaneously operate the first blowing means 14. By the operation of the first blowing means 14, the air in the drying chamber 10 is circulated using the circulation air path 12 provided in the upper part of the drying chamber 10 and the lower part of the drying chamber 10. By this circulation, the adsorbent 11 is placed in the drying chamber 10.
Thus, high-temperature dry air dried is supplied, and clothes such as laundry in the drying room 10 are dried.

When a predetermined time has elapsed since the start of drying, the control means 21 controls the air path switching means 16 and the air path switching means 1.
7 to instruct the regeneration air path 13 to be opened. At the same time, the second air blowing means 43 is operated, and at the same time, an instruction to energize the heating means 15 is issued to execute the regeneration process of the adsorbent 11 described in the first embodiment. The regeneration air blown by the second blowing means 43 passes through the heat exchanger 20,
The adsorbent 1 is heated by the heating means 15 to a high temperature.
Touch 1. The contact of the high-temperature air raises the temperature of the adsorbent 11, and the moisture absorbed by the adsorbent 11 during circulation is released from the adsorbent 11. Thus, the adsorbent 11 is regenerated. The humid regenerated air containing the released water passes through the regenerative air passage 13, passes through the heat exchanger 20, and is exhausted out of the drying chamber 10. At this time, the heat exchanger 20
The second air blowing means exchanges heat between the high-temperature regenerated air passing through the regenerative air passage 13 and the air sucked from outside the drying chamber 10. Therefore, the air sucked from outside the drying chamber 10 is heated and sent to the heating means 15. Therefore, as described in the first embodiment, the amount of heating by the heating means 15 can be reduced and efficient drying can be performed.

As described in the first embodiment, the high-temperature and high-humidity regenerated air containing water released from the adsorbent 11 is supplied from the outside of the drying chamber 10 by the second blowing means 43 in the heat exchanger 20. The heat is exchanged with the cooled air, and the air becomes low temperature and low humidity and is exhausted from the exhaust port 42b and the exhaust port 42c. At this time, since a large amount of cooling air is taken in from the intake port 42a, a small amount of regenerated air passing through the heat exchanger 20 is efficiently exchanged with heat and cooled. That is, the exhaust port 42b,
The cooling air exhausted from the exhaust port 42c has a very low humidity and does not humidify the outside air.

As described above, according to the present embodiment, the adsorbent 1
1 is exchanged with air outside the drying chamber 10 at a relatively low temperature before passing through the adsorbent 11 and the heating means 15 using the heat exchanger 20. By doing so, the thermal energy of the regeneration air can be efficiently recovered. Further, as a result, the regeneration air supplied to the heating means 15 is higher than the temperature of the outside air, so that the amount of heating by the heating means 15 can be reduced,
This realizes a highly efficient dryer. Further, since the regenerated air is dew-condensed using the heat exchanger 20, the amount of water released to the outside of the drying chamber 10 can be reduced, and the outside air is not humidified.

Further, in this embodiment, one heat exchanger 20 is used, and the regeneration air passage and the cooling air passage are used in a divided form. Therefore, two heat exchangers are used by one heat exchanger. An effect equivalent to that of the exchanger can be obtained. In other words, the number of heat exchangers is 1
By using a stand, the number of parts can be reduced.

In this embodiment, the second blowing means 43 is set to 1
As the base, the air path is adjusted to the required air volume by using the regeneration air and the cooling air.
The same effect as that obtained by using two air blowing units can be obtained with a single unit, and the number of parts can be reduced.

In this embodiment, a motor is used for each of the first air blowing means 14 and the second air blowing means 43. However, one motor is commonly used to rotate two fans. It is also possible. Also, the installation positions of the first blowing means 14 and the second blowing means 43 are not particularly limited as long as the air in the drying chamber 10 or the air outside the drying chamber 10 can be blown in a predetermined direction in each air path. It does not do.

(Embodiment 3) Next, a third embodiment of the present invention will be described. FIG. 3 is a sectional view showing the configuration of the present embodiment. The circulation air passage 25 is configured by a duct or the like, is connected to the upper and lower portions of the drying chamber 10, and includes a first air blowing unit 27. Reference numeral 24 denotes an adsorbent that adsorbs moisture from the air in the drying chamber 10. The first blowing means 27 is the circulation air passage 2
The air taken in from the upper part of the drying chamber 10 through 5 is dehumidified by the adsorbent 24 and circulated through the lower part of the drying chamber 10. Reference numeral 26 denotes a regeneration air passage provided in contact with or integral with the circulation air passage 25.
a, 30b, heating means 29 and the adsorbent 24 are arranged. 28a and 28b are a plurality of second blowing means.
The air sucked by the second blowing means 28a from the suction port 28c opened to the outside of the drying chamber 10 passes through the regenerating air passage 26 from the heat exchanger 30a as the regenerating air, and passes through the heating means 29, the adsorbent 24, the heat exchange The air is exhausted from an exhaust port 30c opened to the outside air via the heat exchanger 30a and the heat exchanger 30b. On the other hand, the air outside the drying chamber 10 sucked in by the second blowing means 28b is used as cooling air from the cooling air passage 44 through the heat exchanger 30b.
And is discharged out of the drying chamber 10. The cooling air exchanges heat with the regeneration air that has passed through the heat exchanger 30a in the heat exchanger 30b to cool the regeneration air.

Reference numeral 32 denotes control means for controlling each means. Reference numerals 33a and 33b denote drain holes provided in the regeneration air passage 26 to discharge dew water generated in the heat exchangers 30a and 30b.

The adsorbent 24 used in this embodiment is
Has a configuration as shown in FIG. FIG. 4 is a perspective view showing the configuration of the adsorbent 24. The adsorbent 24 has a configuration in which silica gel or zeolite is molded into a cylindrical shape, and has a honeycomb structure in which a large number of through holes are opened so that air flows in the axial direction as shown in the figure. Further, the adsorbent 24 is configured to be constantly rotated by the rotating means 35. The rotating means 35 includes a rotor motor 36 and a belt 37. That is, the adsorbent 24 rotates as a whole when the rotation of the rotor motor 36 is transmitted by the belt 37. Further, a partition plate 38 and a partition plate 39 are provided on the surface of the adsorbent 24.
And is divided into an adsorption zone 40 and a regeneration zone 41. A circulation air passage 25 is connected to the adsorption zone 40, and the drying chamber 1 to which the first blowing means 27 blows air is used.
The air from 0 is dehumidified and returned to the drying chamber 10 again. The regeneration air passage 26 is connected to the regeneration zone 41, and after the air outside the drying chamber 10 passes through the heating means 29, is sent into the regeneration zone 41, passes through the adsorbent 24, and then passes through the heat exchanger 30a. , 30b through the exhaust port 30c.

As described above, the adsorbent 24 of this embodiment is rotated by the rotating means 35, and alternately rotates between the adsorption zone 40 and the regeneration zone 41. In other words, the adsorbent 24 rotates to dehumidify air in the adsorption zone 40 by rotating, and then is heated and regenerated in the regeneration zone 41, moves to the adsorption zone 40 again, repeats adsorption and regeneration, and passes continuously. It dehumidifies the circulating air.

The operation of this embodiment will be described below. When the user operates an operation unit (not shown) to start the operation, the control unit 32 controls the first blowing unit 27, the second blowing units 28 a and 28 b, the heating unit 29, and the rotor motor 3.
6 is activated. By the first blowing means 27, the drying chamber 10
The air inside circulates through the circulation air passage 25 and the adsorbent 24. The air that has passed through the adsorbent 24 is adsorbed by the adsorbent 24 and dehumidified, and the heat of adsorption is obtained to become high-temperature, low-humidity dry air. Due to the circulation of the drying air, the drying in the drying chamber 10 proceeds. That is, when the drying room 10 is used as a clothes dryer, the clothes contained therein are dried. When the drying room 10 is used as a bathroom, the drying of the bathroom is advanced, and the drying room 10 is dried. In the case of intrusion, drying of intrusion proceeds. At the same time, the air taken in by the second blowing means 28a from the suction port 28c opened outside the drying chamber 10 passes through the heat exchanger 30a and
9 The air heated to a high temperature by the energization of the heating means 29 passes through the regeneration zone 41 of the adsorbent 24 and releases moisture absorbed by the adsorbent 24. Therefore, the adsorbent 20 is regenerated by rotating and passing through the regeneration zone 41, and adsorbs moisture again in the adsorption zone 40. The high-humidity regeneration air containing moisture generated by the regeneration is supplied to the second blowing unit 28a.
The heat exchangers 30a, 3a
The air is exhausted from the exhaust port 30c through the exhaust port 30b. While passing through the heat exchanger 30a, the second blowing means 28a heats the air taken in from the air inlet 28c which is open to the outside air. That is, as described in the first embodiment, the thermal energy of the regeneration air is supplied to the new regeneration air sucked in from the intake port 28c by heat exchange. Therefore, according to the present embodiment,
The humid and relatively high temperature of the regenerated air after passing through the regeneration zone 41 of the adsorbent 24 is transferred to the relatively low temperature drying chamber 10 before passing through the adsorbent 24 and the heating means 29 using the heat exchanger 30a. The heat energy of the regenerated air can be recovered by exchanging heat with the outside air. In the heat exchanger 30b, since a small amount of regeneration air after passing through the heat exchanger 30a is cooled by a large amount of cooling air outside the drying chamber 10, the regeneration air is cooled to a low humidity. . The condensed water generated at this time is drained out of the system through drain holes 33a and 33b provided in the regeneration air passage 26.

According to this embodiment, the adsorbent 24 is rotated by the rotating means 35 so that the adsorbing zone 4
0 and the regeneration zone 41 are alternately passed, so that the adsorption and regeneration steps can be performed simultaneously, and the adsorption and dehumidification can be performed continuously, and a dryer with high dehumidification capacity can be realized. In this embodiment, the rotor motor 36 and the belt 37 are used as the rotating means 35. However, it is also possible to employ a configuration in which the central axis of the adsorbent 24 is directly rotated by a motor, and The method of rotating the agent 24 is not limited.

Further, in this embodiment, as shown in FIG. 4, the regenerated air passes through the adsorbent 24 after passing through the heating means 29. However, the configuration shown in FIG. It is also possible. That is, once the adsorbent 24
It is also conceivable to adopt a configuration in which the air that has passed through is heated by the heating means 29, and the air that has been heated is passed through the adsorbent 24 again. That is, the present embodiment does not particularly limit the flow of the regeneration air passing through the adsorbent 24.

In this embodiment, a motor and a sirocco fan are used as the first blower 27 and the second blowers 28a and 28b. However, the present invention is not limited to this configuration. Also, the first blowing means 27 and the second blowing means 28a, 2
8b, a motor is used.
It is also possible to adopt a configuration in which two or three fans are rotated by sharing one motor. In addition, the installation positions of the first blowing means 27 and the second blowing means 28a and 28b may be any as long as the air in the drying chamber 10 or the air outside the drying chamber 10 can be blown in a predetermined direction in each air path. There is no particular limitation.

(Embodiment 4) Next, a fourth embodiment of the present invention will be described. FIG. 6 is a sectional view showing the configuration of the present embodiment. Portions common to the above embodiments are assigned the same reference numerals, and descriptions thereof are omitted. In this embodiment, the first blowing means 2
7 dehumidifies the air taken in from the upper part of the drying chamber 10 through the circulation air passage 25 with the adsorbent 24, and circulates the air to the lower part of the drying chamber 10. In the regeneration air passage 26, a heat exchanger 31, a heating means 29, and an adsorbent 24 are arranged.

An intake port 45a opened outside the drying chamber 10.
The air taken in by the second blowing means 45 from the heat exchanger 31
Thus, the air is divided and sent to the regeneration air passage 26 side and the cooling air passage 44 side. The regenerated air on the regenerative air path 26 side that has passed through the heat exchanger 31 is exhausted from the exhaust port 31 a that is open to the outside air via the heating means 29, the adsorbent 24, and the heat exchanger 31. On the other hand, the cooling air sucked from the intake port 45a by the second blowing means 45 and passed through the cooling air path 44 is sent to the heat exchanger 31 and exchanged with the regenerated air by the heat exchanger 31. From the drying chamber 10. In addition, 32
Control means for controlling each means. 34 is the regeneration airway 2
6 is a drain hole for discharging the dew water generated in the heat exchanger 31.

Hereinafter, the operation of this embodiment will be described. When the user starts operation by operating an operation unit (not shown), the control unit 32 operates the first blowing unit 27, the second blowing unit 45, the heating unit 29, and the rotor motor 36. The air in the drying chamber 10 is circulated through the circulation air passage 25 and the adsorbent 24 by the first blowing means 27. The air that has passed through the adsorbent 24 is adsorbed by the adsorbent 24 and dehumidified, and the heat of adsorption is obtained to become high-temperature, low-humidity dry air.
Due to the circulation of the drying air, the drying in the drying chamber 10 proceeds. At the same time, the drying chamber 1 is
The air is separately blown to the air regeneration air passage 26 and the cooling air passage 44 which are taken in from the intake port 45a opened to the outside as regeneration air and cooling air. The regeneration air is supplied to the heat exchanger 31
And is sent to the heating means 29. The air heated to a high temperature by the energization of the heating means 29 passes through the regeneration zone 41 of the adsorbent 24 and releases moisture absorbed by the adsorbent 24. The high-humidity regeneration air containing moisture generated by the regeneration is exhausted from the exhaust port 31a through the heat exchanger 31. While passing through the heat exchanger 31, the second regenerating air sucked by the second blowing means 45 is heated. That is, the thermal energy of the regeneration air is supplied to new regeneration air sucked from the intake port 45a by heat exchange. Therefore, according to the present embodiment, the regeneration zone 4 of the adsorbent 24 is also used.
1 is exchanged with the air outside the drying chamber 10 at a relatively low temperature before passing through the adsorbent 24 and the heating means 29 using the heat exchanger 31. By doing so, the thermal energy of the regeneration air can be recovered. At this time, according to the present embodiment,
A small amount of regenerated air after regeneration is further cooled by the heat exchanger 31 by a large amount of cooling air outside the drying chamber 10 that is sucked in by the second blowing means 45. For this reason,
The regeneration air condenses to release moisture, becomes low in humidity, and is exhausted from the exhaust port 31a. Therefore, according to the present embodiment, the humidity outside the drying chamber 10 is not increased by the exhaust air. The condensed water generated at this time is drained out of the system from a drain hole 34 provided in the regeneration air passage 26.

In this embodiment, the regeneration air after passing through the adsorbent 24 is supplied to the intake port 4 using one heat exchanger 31.
The heat exchange is performed with new regeneration air and cooling air taken in from 5a. At this time, the air to be taken in is internally partitioned into the regeneration air passage 26 side and the cooling air passage 44 side. Therefore, the same effect as when two heat exchangers are used can be obtained with one heat exchanger 31, and the number of heat exchangers can be reduced.

In this embodiment, one second blowing means 4
5, the air volume required for the regeneration air and the cooling air is obtained by partitioning the inside. Therefore, 1
Even with the two second air blowers 45, the same effect as when two second air blowers are used can be obtained, and the number of parts can be reduced.

In this embodiment, a motor and a centrifugal sirocco fan are used as the second blowing means 45.
It is not limited to this configuration. In addition, although the motor is used for each of the first blowing means 27 and the second blowing means 45, it is also possible to adopt a configuration in which one motor is shared and two fans are rotated. Also, the installation positions of the first blowing means 27 and the second blowing means 45 are not particularly limited as long as the air in the drying chamber 10 or the air outside the drying chamber 10 can be blown in a predetermined direction in each air path. It does not do.
